"Download object" contents not populated most of the time

[richlv]

1. Download a way
2. Select this way, search for "child selected"
3. Copy the found nodes
4. File -> Download object

Rarely, the nodes are populated in the download field. Most often, nothing is populated.
This is a problem, as just pasting it in the "Object ID" field gets a format like "node 1431642962
node 1431646044
node ", newlines not displayed - and this format is not considered valid.

This _might_ be related to the number of the nodes in the way (and clipboard) - it might be failing for longer ways.

That is, exactly where this functionality would be the most useful.
Usecase: deleting a pretty long and windy way, so that lots and lots of data around it is not downloaded.

Cannot add status output, as it does not pass the "external link" check.

Cannot add status output as a comment either, "Maximum number of external links per post exceeded".

You can change the advanced preference downloadprimitive.max-autopaste-length. The default is 2000, and the specified nodes are part of a way with 239 nodes, and the number of characters for that is 3823.

To fix this issue, someone will need to listen for a paste event of some kind, and then handle it.

For this specific use case, "deleting a pretty long and windy way" I would recommend using overpass instead of the Download object window. In order to safely delete the long way given the nodes, we have to get the referrers. This is 2 API calls per node, which on my system took ~.8s. This would take you ~3 minutes to download (191.2s).

The equivalent overpass query looks like this:

[out:xml][timeout:90];
(
  way(1038063792);
  >; // Recurse down (get the nodes)
  <; // Recurse up (get the node parents)
);
(._;>;);
out meta;

I do not understand why Debian changes the ReportBug action to point to reportbug(1). @sebastic might know more about the reason.
Anyway, please, have a look at the table at Show Status Report. We only need the first parts. If it still does not work, you could try to attach it as file. At least as compressed file it should work. Thanks.

Because the josm package in Debian is built differently from the upstream jars, issues specific to the package in Debian (not the upstream packaging) should be reported in the Debian BTS.

If you're happy to receive tickets for issues that may be caused by downstream changes, I'll happily drop the 'Report bug' changes to have it use Trac again.

[taylor.smock]

Taking a look at ​https://salsa.debian.org/debian-gis-team/josm/-/tree/master/debian/patches, the only ones I have issues with are 00-build.patch (due to the commenting out of code -- I get the ivy stuff, but I don't know why you are commenting out other items) and 09-no-java-8.patch.

For 09-no-java-8.patch, it should be unnecessary due to trunk/build.xml@18587:80,220#L220​ (we compile with --release 8). I didn't see any modification to the java.lang.version in 00-build.patch. Docs indicate that Java 17 should compile bytecode with the appropriate method calls for Java 8. But we are planning on dropping Java 8 support soon, so I'm not going to complain too much.

If you're happy to receive tickets for issues that may be caused by downstream changes, I'll happily drop the 'Report bug' changes to have it use Trac again.

Looking at ​bugs.debian.org, it looks like there have been a total of two bugs reported against the package.

My recommendation (note: other maintainers may disagree):

• Add a line in the bug report window for the current maintainer of the JOSM Debian package. Use the username you have for JOSM trac (sebastic). That way a new contributor can look at the ticket and the code, and then reassign it to you if it didn't occur in our code.

The Debian packages uses javac instead of ErrorProne, so we kept using the ant config for as before.

That may have changed in the mean time, when default-jdk in Debian switched from openjdk-8 to openjdk-11 running josm with openjdk-8-jre was broken.

The dependencies reflect this too:

Build-Depends: debhelper-compat (= 12),
               default-jdk (>= 2:1.9) | java9-sdk,

Depends: default-jre (>= 2:1.9) | java9-runtime,

You're missing the archived bugreports:

​https://bugs.debian.org/cgi-bin/pkgreport.cgi?archive=both;package=josm

That breaks when I get hit by a bus. The team is listed as Maintainer for the Debian package for that reason.

CC'ing me here in Trac works to get my attention, but not others in the Debian GIS team.

In that case, lets keep the status quo, but maybe there should be reportbug/reportbug-gtk integration instead of linking users to bugs.debian.org. I (personally) think [that just giving users a link] is useless -- many people won't bother to report a bug if they have to follow a few links to figure out how to report the bug.

Status report: attached as a txt file.

Debian: not sure how that got pulled in, this was observed with a Mac version.

Overpass suggestion: that's excellent, thank you :)

Original issue: spent a long time trying and retrying this in various combinations... Can some warning be shown when autopaste fails because of "max-autopaste-length"?
